[Solved] Number of processors \ cores under Linux
« on: February 11, 2020, 11:39:27 am »
Hello,

I would like to get the number of processors of a PC running Linux, to limit the maximum number of workers created at the same time, to this number.
Under Windows, there is GetSystemInfo. Do you know the equivalent under Linux?

Regards.
